A Personal Adventure in Stereochemistry Local Order and Defects: Models for Room-Temperature Superconductivity

  • Stanford R. Ovshinsky
Part of the Institute of Amorphous Studies Series book series (IASS)


The relationship between electronic conduction and stereochemical local bonding arrangements is illustrated by four examples: the unusual high conductance ON-state of the Ovonic Threshold Switch resulting from nonequilibrium excitation processes the high conductivity connected with the oxidation states of the Ovitron, the chemical modification of electronic transport in amorphous semiconductors and insulators, and the high temperature copper oxide ceramic superconductors. We discuss the effect of fluorination on raising the superconducting transition temperature to Tc=155K or higher, on eliminating oxygen diffusion and on orienting the crystallites in the YBaCuO superconductors.

    I hope that Heinz forgives me my emphasis on lone pairs. Certainly other carriers can initiate and make up a highly dense plasma, but the presence of lone pairs also in nonchalcogenide materials such as in group V, albeit not as pronounced or available, still must be taken into account. In any case, we have seen some forms of threshold switching in nonchalcogenide materials early at ECD and later at Penn State (K. Homma, H.K. Henisch and S.R. Ovshinsky, J. Noncryst. Solids 35&36:1105 (1980)) which indicates to me that there is a possibility of the critical on-state plasma being present in a spectrum of materials. However, there is no question that the switching mechanism is best seen and most stable in the lone-pair chalcogenides since the excitation process occurs in the nonbonded lone pairs rather than in the structural bonds as it does in other materials. It is in these materials that the effective negative correlation energy reigns supreme and that the volumetric control of the constant current density of the filament is best expressedGoogle Scholar
